Abstract
BACKGROUND It is necessary to develop a safe alternative to isoniazid for tuberculosis prophylaxis in liver transplant recipients. This study was designed to investigate the efficacy and safety of levofloxacin. METHODS An open-label, prospective, multicenter, randomized study was conducted to compare the efficacy and safety of levofloxacin (500 mg q24h for 9 months) initiated in patients awaiting liver transplantation and isoniazid (300 mg q24h for 9 months) initiated post-transplant when liver function was stabilized. Efficacy was measured by tuberculosis incidence at 18 months after transplantation. All adverse events related to the medication were recorded. RESULTS CONSORT guidelines were followed in order to present the results. The safety committee suspended the study through a safety analysis when 64 patients had been included (31 in the isoniazid arm and 33 in the levofloxacin arm). The reason for suspension was an unexpected incidence of severe tenosynovitis in the levofloxacin arm (18.2%). Although the clinical course was favorable in all cases, tenosynovitis persisted for 7 weeks in some patients. No patients treated with isoniazid, developed tenosynovitis. Only 32.2% of patients randomized to isoniazid (10/31) and 54.5% of patients randomized to levofloxacin (18/33, P = .094) completed prophylaxis. No patient developed tuberculosis during the study follow-up (median 270 days). CONCLUSIONS Levofloxacin prophylaxis of tuberculosis in liver transplant candidates is associated with a high incidence of tenosynovitis that limits its potential utility.

Abstract
BACKGROUND & AIMS The seroprevalence of the hepatitis E virus (HEV) and its chronicity rate in the HIV-infected population has not been well established. As a result, the magnitude of this emerging disease in this population cannot be established. METHODS Prospective study that included HIV-infected patients followed up between September 2012 and May 2013. All included patients were tested for anti-HEV IgG/IgM. In patients with confirmed anti-HEV IgG/IgM positivity, RT-PCR was performed. In patients where HEV RNA was amplified, a second RT-PCR assay was performed 6 months later to identify transient or chronic HEV infections. RESULTS Eight hundred and ninety-four HIV-infected patients were enrolled in the study. Of these patients, 399 (44.6%) were monoinfected with HIV; 462 (51.6%) were co-infected with HIV/HCV; 12 (1.3%) were co-infected with HIV/HBV; and 21 (2.3%) were co-infected with HIV/HCV/HBV. In 88 patients, anti-HEV IgG/IgM was detected (seroprevalence: 9.8% [95% CI: 8.02%-11.9%]). In five patients (0.5%; 95% CI: 0.2%-1.2%), HEV RNA was detected; 5.7% (95% CI: 2.1%-12.1%) of the patients were anti-HEV IgG/IgM positive. None of these patients showed detectable HEV RNA six months later. CONCLUSION HEV infection is frequent in HIV-infected patients but developing a chronic HEV infection may be considered an uncommon liver disease in this population.

Abstract
BACKGROUND Despite administration of annual influenza vaccination, influenza-associated complications in transplant recipients continue to be an important cause of hospitalization and death. Although influenza vaccination has been proven to be the most effective measure to reduce influenza infection after transplantation, transplant recipients are still vulnerable to influenza infections, with lower serological responses to vaccination compared to the general population. In order to assess the efficacy and safety of an alternative immunization scheme for solid organ transplant recipients, the TRANSGRIPE1-2 Study Group aimed to test a booster dose administration 5 weeks after the standard vaccination. The primary objective of this trial was to compare short-term and long-term neutralizing antibody immunogenicity of a booster dose of influenza vaccination to the standard single-dose immunization scheme. Secondary objectives included the evaluation of the efficacy and/or safety, cellular immune response, incidence of influenza infection, graft rejection, retransplant and mortality rates. METHODS/DESIGN This phase III, randomized, controlled, open-label clinical trial was conducted between October 2012 and December 2013 in 12 Spanish public referral hospitals. Solid organ transplant recipients (liver, kidney, heart or lung), older than 16 years of age more than 30 days after transplantation were eligible to participate. Patients (N = 514) were stratified 1:1 by center, type of organ and time after transplantation and who either received the standard single dose (n = 257) or were treated according to a novel influenza vaccination schedule comprising the administration of a booster dose 5 weeks after standard vaccination (n = 254). Seroconversion rates were measured as a determinant of protection against influenza (main outcome). Efficacy and safety outcomes were followed until 1 year after influenza vaccination with assessment of short-term (0, 5, 10 and 15 weeks) and long-term (12 months) results. Intention-to-treat, per-protocol and safety analyses will be performed. DISCUSSION This trial will increase knowledge about the safety and efficacy of a booster dose of influenza vaccine in solid organ transplant recipients. At the time the manuscript was submitted for publication, trial recruitment was closed with a total of 499 participants included during a 2-month period (within the seasonal influenza vaccination campaign). TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT01761435 (registered 13 December 2012). EudraCT Identifier: 2011-003243-21 (registered 4 July 2011).

Abstract
We determined the characteristics of posttransplant tuberculosis and the impact of rifampin-based antituberculosis regimens on outcomes in the current era. Patients comprised 64 transplant recipients with tuberculosis, divided into 2 consecutive cohorts: an earlier cohort (cases occurring from 2003 to 2007) and a later cohort (cases from 2008 to 2011). Patients from the later versus earlier era had tuberculosis develop later after transplant (odds ratio, 1.01; 95% CI, 1.00-1.02; P= .05), were more likely to be liver transplant recipients (odds ratio, 4.52; 95% CI, 1.32-15.53; P= .02), and were more likely to receive tacrolimus-based immunosuppression (odds ratio, 3.24; 95% CI, 1.14-9.19; P= .03). Mortality rate was 10% in the later cohort and 21% in the earlier cohort (P= .20). Rifampin-based treatment was less likely to be used in patients with prior rejection (P= .04). However, neither rejection rate (P= .71) nor mortality (P= .93) after tuberculosis differed between recipients who received rifampin and recipients who did not. Thus, notable changes have occurred in the epidemiological characteristics of tuberculosis in transplant recipients. Overall mortality rate has improved, with about 90% of the patients now surviving after tuberculosis.

Abstract
INTRODUCTION Infections caused by resistant gram-positive cocci (GPC), especially to glycopeptides, are difficult to treat in solid organ transplant (SOT) recipients as a result of lower effectiveness and high rates of renal impairment. The aim of this study was to evaluate the use of daptomycin in this population. METHODS Over a 2-year period (March 2008-2010) in 9 Spanish centers, we enrolled all consecutive recipients who received daptomycin to treat GPC infection. The study included 43 patients, mainly liver and kidney transplant recipients. RESULTS The most frequent infections were catheter-related bacteremia caused by coagulase-negative staphylococci (23.2%), skin infection caused by Staphylococcus aureus (11.5%), and intra-abdominal abscess caused by Enterococcus faecium (20.9%). The daily daptomycin dose was 6 mg/kg in 32 patients (74.4%). On day 7 of daptomycin treatment, median estimated area under the curve was 1251 μg/mL/h. At the end of follow-up, analytical parameters were similar to the values at the start of therapy. No changes were observed in tacrolimus levels. No patient required discontinuation of daptomycin because of adverse effects. Clinical success at treatment completion was achieved in 37 (86%) patients. Three patients died while on treatment with daptomycin. CONCLUSION In summary, daptomycin was a safe and useful treatment for GPC infection in SOT recipients.

Abstract
BACKGROUND Cytomegalovirus (CMV)-negative recipients of a graft from a CMV-positive donor (D+/R-) are at high risk of CMV disease. Current preventive strategies include universal prophylaxis (UP) and preemptive therapy (PT). However, the best strategy to prevent CMV disease and achieve better long-term outcomes remains a matter of debate. METHODS We analyzed the incidence of CMV disease and long-term outcomes including graft dysfunction and patient mortality at 5 years after transplantation with both preventive strategies. High-risk (D+/R-) kidney and liver transplant recipients from the RESITRA cohort were included. RESULTS Of 2410 kidney or liver transplant patients, 195 (8.3%) were D+/R-. The final cohort included 58 liver and 102 kidney recipients. UP was given in 92 patients and 68 received PT; 10.9% and 36.8% developed CMV disease, respectively (P < 0.01). The independent risk factors for CMV disease were PT strategy (hazard ratio [HR], 3.30; 95% confidence interval [CI], 1.6-6.9), kidney transplantation (HR, 3.8; 95% CI, 1.4-9.9), and cyclosporine immunosuppression (HR, 2.4; 95% CI, 1.2-4.7). PT strategy was also a risk factor for CMV disease in both liver transplantation (HR, 11.0; 95% CI, 1.2-98.7) and kidney transplantation (HR, 2.7; 95% CI, 1.3-6.0), independently. The development of CMV replication during the first 2 years after transplantation was a risk factor for graft dysfunction at 5 years after transplantation (odds ratio, 3.4; 95% CI, 1.3-9.0). Nevertheless, no significant differences were seen in either graft dysfunction or mortality between the 2 strategies. CONCLUSIONS The study supports the benefit of the UP strategy to prevent CMV disease in D+/R- liver or kidney transplant patients. The development of CMV replication during the first 2 years after transplantation was associated with graft dysfunction at 5 years after transplantation.

Abstract
OBJECTIVE To evaluate the IL28B effect on hepatitis C virus (HCV) decline during first weeks of treatment according to HCV-1 subtypes. METHODS Patients coinfected with HIV/HCV genotype 1 and naive to peginterferon-alpha-2a and ribavirin (Peg-IFN-alpha-2a/RBV) were included. Plasma HCV-RNA was measured at baseline, and then at weeks 1, 2, and 4. HCV-1 subtype (1a or 1b) was determined. HCV viral decline was analyzed according to HCV-1 subtype between baseline and week 1, week 2 and week 4 of treatment. Additionally, we analyzed the effect of the IL28B (rs12979860) genotype on HCV viral decline with HCV-1a and HCV-1b genotype patients (CC versus non-CC). RESULTS Two hundred and six patients were included in the study, of whom 113 (54.8%) and 93 (45.2%) were infected by HCV-1a and 1b genotypes, respectively. No differences were found between HCV-1 subtypes in terms of HCV viral decline or rapid virological response rate. The effect of the IL28B-CC genotype on HCV viral decline was observed only among patients infected with HCV-1b at all time points analyzed (week 1: CC 1.53 ± 0.33, non-CC 0.27 ± 0.24, P <0.001; week 2: CC 1.81 ± 0.39, non-CC 0.74 ± 0.39, P = 0.002; week 4: CC 2.97 ± 0.53, non-CC 1.2 ± 0.61, P < 0.001). CONCLUSION Our study suggests that the effect associated with the impact of the IL28B-CC genotype on HCV decline during the first weeks of treatment with Peg-IFN-alpha-2a/RBV differs according to HCV-1 subtype and may be limited to HCV-1b patients.

Abstract
In this prospective study we analyzed pretransplant interferon-γ secretion by cytomegalovirus (CMV)-specific CD8+ T cells to assess its possible utility in determining the risk of CMV replication after solid organ transplantation. A total of 113 lung and kidney transplant patients were enrolled in the study but only 55 were evaluable. All CMV-seronegative recipients were pretransplant "nonreactive" (IFNγ <0.2 IU/mL) (11/11), whereas 30/44 (68.2%) CMV-seropositive (R+) recipients were "reactive" (IFNγ ≥0.2 IU/mL) and 14/44 (31.8%) were "nonreactive". In the R(+) "nonreactive" group, 7/14 (50%) developed posttransplant CMV replication, whereas the virus replicated only in 4/30 (13.3%) of the R(+) "reactive" patients (p = 0.021). According to the best multivariate model, pretransplant "nonreactive" recipients receiving an organ from a CMV-seropositive donor had a 10-fold increased risk of CMV replication compared to pretransplant "reactive" recipients (adjusted OR 10.49, 95% CI 1.88-58.46). This model displayed good discrimination ability (AUC 0.80) and calibration (Hosmer-Lemeshow test, p = 0.92). Negative and positive predictive values were 83.7% and 75%, respectively. The accuracy of the model was 82%. Therefore, assessment of interferon-γ secretion by cytomegalovirus (CMV)-specific CD8+ T cells prior to transplantation is useful in informing the risk of posttransplant CMV replication in solid organ transplant patients.

Abstract
Eighty-four HCV/HIV-coinfected and 252-matched HCV-monoinfected liver transplant recipients were included in a prospective multicenter study. Thirty-six (43%) HCV/HIV-coinfected and 75 (30%) HCV-monoinfected patients died, with a survival rate at 5 years of 54% (95% CI, 42-64) and 71% (95% CI, 66 to 77; p = 0.008), respectively. When both groups were considered together, HIV infection was an independent predictor of mortality (HR, 2.202; 95% CI, 1.420-3.413 [p < 0.001]). Multivariate analysis of only the HCV/HIV-coinfected recipients, revealed HCV genotype 1 (HR, 2.98; 95% CI, 1.32-6.76), donor risk index (HR, 9.48; 95% CI, 2.75-32.73) and negative plasma HCV RNA (HR, 0.14; 95% CI, 0.03-0.62) to be associated with mortality. When this analysis was restricted to pretransplant variables, we identified three independent factors (HCV genotype 1, pretransplant MELD score and centers with <1 liver transplantation/year in HIV-infected patients) that allowed us to identify a subset of 60 (71%) patients with a similar 5-year prognosis (69%[95% CI, 54-80]) to that of HCV-monoinfected recipients. In conclusion, 5-year survival in HCV/HIV-coinfected liver recipients was lower than in HCV-monoinfected recipients, although an important subset with a favorable prognosis was identified in the former.

Abstract
BACKGROUND Urinary tract infection (UTI) is the most common infection in renal transplant patients, but it is necessary to determine the risk factors for bacterial UTI in recipients of other solid organ transplants (SOTs), as well as changes in etiology, clinical presentation, and prognosis. METHODS In total, 4388 SOT recipients were monitored in 16 transplant centers belonging to the Spanish Network for Research on Infection in Transplantation (RESITRA). The frequency and characteristics of bacterial UTI in transplant patients were obtained prospectively from the cohort (September 2003 to February 2005). RESULTS A total of 192 patients (4.4%) presented 249 episodes of bacterial UTI (0.23 episodes per 1000 transplantation days); 156 patients were kidney or kidney-pancreas transplant recipients, and 36 patients were liver, heart, and lung transplant recipients. The highest frequency was observed in renal transplants (7.3%). High frequency of cystitis versus pyelonephritis without related mortality was observed in both groups. The most frequent etiology was Escherichia coli (57.8%), with 25.7% producing extended-spectrum β-lactamase (ESBL). In all transplants but renal, most cases occurred in the first month after transplantation. Cases were uniformly distributed during the first 6 months after transplantation in renal recipients. Age (odds ratio [OR] per decade 1.1, 95% confidence interval [CI] 1.02-1.17), female gender (OR 1.74, 95% CI 1.42-2.13), and the need for immediate post-transplant dialysis (OR 1.63, 95% CI 1.29-2.05) were independent variables associated with bacterial UTI in renal and kidney-pancreas recipients. The independent risk factors identified in non-renal transplants were age (OR per decade 1.79, 95% CI 1.09-3.48), female gender (OR 1.7, 95% CI 1.43-2.49), and diabetes (OR 1.02, 95% CI 1.001-1.040). CONCLUSIONS UTI was frequent in renal transplants, but also not unusual in non-renal transplants. Because E. coli continues to be the most frequent etiology, the emergence of ESBL-producing strains has been identified as a new problem. In both populations, most cases were cystitis without related mortality. Although the first month after transplantation was a risk period in all transplants, cases were uniformly distributed during the first 6 months in renal transplants. Age and female gender were identified as risk factors for UTI in both populations. Other particular risk factors were the need for immediate post-transplant dialysis in renal transplants and diabetes in non-renal transplants.

Abstract
OBJECTIVE To evaluate the effect of low-density lipoprotein receptor (LDLr) and IL28B genotypes on hepatitis C virus (HCV) viral kinetics in the first 4 weeks of treatment with pegylated-interferon (PEG-IFN)/ribavirin (RBV) in HIV patients co-infected with HCV genotype 1. METHODS HIV patients co-infected with HCV genotype 1 and naïve to PEG-IFN/RBV treatment were enrolled in a prospective study. HCV RNA viral loads were measured at baseline and at weeks 1, 2 and 4 after start of therapy. Differences in viral load decline were evaluated for IL28B (CC versus non-CC) and LDLr (CC versus non-CC) genotypes between baseline and weeks 1, 2 and 4. Additionally, the effect of LDLr genotype on HCV viral decline in IL28B CC genotype patients (CC/CC versus CC/non-CC) was analyzed. RESULTS Eighty-seven HIV/HCV genotype 1 co-infected patients were included in the study. Patients carrying the LDLr-CC or IL28B-CC genotypes showed greater HCV viral decline than those with IL28B non-CC or LDLr non-CC genotypes at every time-point analyzed. CC/CC patients had higher rapid virological response (RVR) rates than CC/non-CC patients (41.2 versus 13.3%; P < 0.001). Moreover, at all time points, the CC/CC pattern was associated with greater HCV viral decline than the CC/non-CC genotype (week 1: 1.18 ± 0.51 versus 0.31 ± 0.29, P = 0.041; week 2: 1.55 ± 0.81 versus 0.93 ± 0.73, P = 0.032; week 4: 2.23 ± 1.1 versus 1.5 ± 0.94, P = 0.039). CONCLUSION The LDLr genotype impacts on viral kinetics during the first days of starting treatment with PEG-IFN/RBV in HIV/HCV genotype 1 co-infected patients, and modifies the impact of IL28B on HCV viral decay.

Abstract
Concern has been raised regarding the response to vaccination in solid organ transplant recipients (SOTR) undergoing immunosuppressant regimens and the possibility of rejection related to the immune response associated with pandemic influenza H1N1-2009 vaccination. The goal of this study was to assess the immunogenicity, efficacy and safety of the pandemic vaccine in SOTR. We performed a multicenter prospective study in SOTR receiving the pandemic vaccine. Immunological response was determined in serum 5 weeks after vaccination by microneutralization assays, and immunoglobulins were measured by ELISA. Three hundred and forty-six SOTR were included. Preexisting seroprotection was detected in 13.6% of cases and rates of seroconversion and seroprotection after vaccination were 73.1% and 82.9%, respectively. Patients with baseline antibody titers had better geometric mean titers (GMT)-post after pandemic vaccination (339.4 vs. 121.4, p < 0.001). Younger age, liver disease and m-TOR inhibitor therapy were independently associated with lower seroprotection and GMT-post. There were no major adverse effects or rejection episodes. Pandemic vaccine was safe in SOTR and elicited an adequate response, although lower than in healthy individuals. This is the first study describing a decreased response after vaccination in patients receiving mTOR inhibitors who presented lower seroprotection rates and lower GMT-post.

Abstract
The role of selective intestinal decontamination with fluoroquinolones (FQ-SID) in the prevention of early bacterial infections (EBIs) in liver transplant recipients (LTRs) is unknown. We used the online database of the Spanish Network of Infection in Transplantation/Spanish Network for Research in Infectious Diseases, which prospectively analyzed 1010 LTRs from 12 Spanish hospitals from September 2003 to February 2005. We compared the incidence and etiology of EBIs (30 days after transplantation) in 415 LTRs from 4 centers that used FQ-SID (>7 days) and in 595 LTRs from 8 hospitals that did not use FQ-SID. A multivariate logistic regression analysis (including an adjustment for the transplant center factor) was performed to evaluate the potential protective factor of FQ-SID in the development of EBIs. We reported 266 EBI episodes in 252 LTRs (incidence = 24.9%). There were no differences in the incidence of EBIs between patients in the FQ-SID group and patients not in the FQ-SID group [109/415 (26.3%) versus 143/595 (24%), P = 0.9]. Although LTRs who received FQ-SID had a lower incidence of infections due to enteric bacteria (2.7% versus 6.5%, P = 0.007) and a higher incidence of infections due to nonfermenting gram-negative bacilli (6.6% versus 2.6%, P = 0.004), these findings could not be confirmed after an adjustment by the center factor in the multivariate models. We found no significant differences in the incidence of enterococcal infections (3.4% with FQ-SID versus 3.9% without FQ-SID, P = 0.5). Multivariate analysis did not confirm any protective effect of FQ-SID against the development of EBIs by enteric bacteria. In conclusion, FQ-SID does not reduce the incidence of EBIs in LTRs and could be withheld from this group of patients.

Abstract
OBJECTIVE The aim of the study was to describe the clinical presentation and prognosis in HIV-1-infected patients with hospital admission and pandemic influenza A 2009 (H1N1) confirmed, and compare this data with those of a general population. DESIGN : This is a prospective study in nature. METHODS All adult patients admitted to 13 hospitals in Spain with confirmed influenza A 2009(H1N1) virus infection by real-time reverse transcriptase PCR assay or culture from June 12 to November 10, 2009 were recruited and followed up until 1 month after discharge. In the HIV group risk factors for HIV infection, AIDS criteria, last CD4 cell count and viral load, and antiretroviral therapy and pneumococcal vaccines were collected. RESULTS Five hundred and eighty-five patients were recruited, 26 with HIV-1 infection and 559 non-HIV. The HIV patients had a long-term well controlled infection with a median CD4 cell count 503 cells/μl and 84% with undetectable viral load, although more frequently they had chronic liver and chronic obstructive pulmonary disease. No significant differences were observed about reported symptoms and physical findings on hospital admission. About 50% of patients in both groups present radiological infiltrates and 30% present respiratory failures. Practically all the patients in both groups received influenza antiviral therapy and in each group 80% received antibacterial therapy. No differences were observed in clinical outcomes. CONCLUSION In HIV patients, well controlled on HAART, the pandemic influenza virus AH1N1 had a similar clinical outcome and prognosis to that of non-HIV patients.

Abstract
This paper analyses the effect of hypothyroidism on pancreatic TRH and somatostatin concentrations, as well as the action of exogen TRH on pancreatic amylase secretion from isolated lobules and dissociated acini of both healthy and hypothyroid rats. In the hypothyroid group, pancreatic TRH and somatostatin increased. In the pancreatic lobules of untreated animals, bethanechol produced stimulatory action that was inhibited by TRH. On the other hand, lobules from hypothyroid rats did not respond to bethanechol stimulation. Acini amylase secretion after bethanechol stimulation was similar in both groups, although hypothyroid animals were more sensitive to the inhibitory effect of TRH. These findings suggest the existence of a factor blocking the amylase secretion in pancreatic lobules. This agent, probably TRH, could be eliminated in the experimental model of dissociated acini.

Abstract
Invasive fungal infection is a growing cause of morbidity and mortality in immunosuppressed patients. Furthermore, the use of azole prophylaxis against Candida species has coincided with an increase in the incidence of invasive aspergillosis and infections by other filamentous fungi such as Mucorales. New risk factors and different timescales for onset have been identified. Knowledge of changes in the epidemiology of, and risk factors for, invasive fungal infection is particularly important when developing therapeutic strategies and effective prophylaxis to improve the prognosis of immunosuppressed patients.
